Effects of Magnetohydrodynamic Interaction-Zone Position on Shock-Wave/Boundary-Layer Interaction

DNS of unsteady shock boundary layer interaction

A novel numerical scheme has been developed to simulate high speed viscous flows in complex geometries using unstructured grids. A characteristic–filter based shock capturing scheme is applied as a corrector step to a non–dissipative predictor scheme. This algorithm is being used to study shock turbulent boundary layer interactions and this paper presents the results of a turbulent flow at Mach...

Shock Wave / Boundary Layer Interaction Experiment on Control Surface

The shock wave / boundary layer interaction (SWBLI) experiment is part of the EXPERT mission. SWBLI is studied on two identical fixed compression ramps made of C/SiC, which are models for control surfaces. The flow separates on the flat surfaces upstream of the compression ramps and reattaches on the ramp surfaces. A reattachment shock results, which interacts with the boundary layer. One ramp ...

Effects of Suction on the Interaction between Shock Wave and Boundary Layer at a Compression Corner

Optimization of MVG for Control of Shock Boundary Layer Interaction

Based on the new theory of MVG to reduce separation caused by shock boundary layer interaction (SBLI), a new optimization method is presented in this paper. The key issue is to generate a proper momentum deficit zone, which can generate a strong shear layer and further strong vortex rings frequently, in front of shock. Several artificial momentum deficit zones (low speed streaks) are tested by ...
